This application has to do with improvements on the devices shown, described and claimed in an application led by Roland A. Furlong and James R. Clark on November Serial No. 317,179. It has for its principal object to provide an improved card holder which shall be of simple and inexpensive construction, easy to form in manufacture, readily manipulated by the operator in use and durable for its purpose. A further the accompanying drawings,

object of the invention is to incorporate, in such a card holder, means to facilitate the ready engagement and disengagement therewith of visible indexcards having hinge elements. l j

The improvements will be made clear 1n connection with the embodiment shown in wherein Figure 1 is a view in plan of the improved card holder.

Figure 2 is a view in end elevation thereof.

Figure 3 is a sectional view taken .on the plane indicated bythe line 3-3 of Figure 1 and looking in the direction of the arrows.

Figure 4 is a view in plan showing a single index card engaged with the holder illustrated in Figure 1.

Figure 5 is a sectional view on the plane indicated by the line 5-5 yof Figure 4 and looking in the direction of the arrows.

Figure 6 is a s-ectional View similar to Figure 5 but showing a similar hinge applied to a double index card.

Figure 7 is a view similar to Figure 1.

Figure 8 is a view in plan showing two pairs of hinges engaged with dierent groups of cards engaged with spaced slotted restrictions in the card holder. v

Figures 9 and 10 are sectional views taken on the planes indicated by the lines 9-9 and 10-10, respectively, of Figure 8 and looking in the direction of the arrows. v

The improved card holder a in its preferred form is made from sheet aluminum or any other material of suitable strength which can be readily stamped and formed. From the blank is formed a channel I), in crossjsection, and at spaced intervals'along the length of the card holder the side walls of the channel are drawn together to provide, in the illustrated embodiment, a restricted slotted portion o adjacent one end of the card holder, and two spaced slotted restricted portions b2 and b3 adjacent the other end of the card holder. At the inner end of each of these Vslots the side walls of the channel may be drawn completely together as indicated at b4 so as to provide limit stops at the ends of the slots to hold the hinges against relative movement therein as will appear more clearly hereinafter. Each of the slotted portions b2, b3, has its open end presented towards the mid-section of the holder a, their limit stops serving to close their other ends, respectively. In thus forming the walls of the channel in the manner described it will be clear from Figures 2 and 3 that they are inclined and their cross-sectional form will add materially'to the stiffness and strength longitudinally of the card holder. These desirable characteristics are thus accomplished in the simplest possible manner and without additional operations while the desired provision is made for mounting of the cards. Thearticle is sturdy, light in weight, easy to produce in quantity by simple forming operations and convenient for use by the operator. If desired, to facilitate its endwise movement in the tray, notches b5 adjacent its opposite ends may be cut out for engagement by the finger or a suitable tool to facilitate movement of the card holder in the tray.

The index cards which are to be mounted in the holder must carry hinge members for engagement with the slots b and b3 or any two of them of the slots b2 or b3. The most suit-able form of hinge is described inthe said copending application and consists of a piece of fabric c which may be glued to the opposite side faces of a card d and enlarged at its fold, as'by a fold c therein. The restricted slots b', b2 and b3 are less in width than the diameter of the fold c on the hinge. The channeled portion?) of the holder a is of sufficient length adjacent the open end sie' of each one of the slots YJ', b2, b3 toreceive' I hinge of the card d Will be introduced into the channel adjacent the one end of the slot and then slid along the slot with the cord-enlarged told engaged by the Walls of the holder. Vhen the hinge element has reached the end of the slot ZJ, the card may be bent suiiiciently to introduce the righthand hinge in the open channel adjacent the open end of the slot b3 whereby the told may be slid along the channel under the slot until the Card lies tlatwise as illustrated in Figure t.

If a folded card is used providing tivo sheets as indicated at d', (Z2, in Figure 6 the hinge c can be glued to the outer faces thereof as previously7 described and the hinges will be engaged with the holder exactly as though a single card (Z Were carried.

In Figures 8, 9 and l() the cards affording three sheets are illustrated as mounted in the holder. Thus, one card e has its hinges indicated in dotted lines at c', e2 ot the Figure 8 and another double card presents two sheets f. f2 shown as having hinge members f2, The double card j", f, is tirst mounted by enits hinges f2, f3. With the spaced slots b, 3 as described With reference to Figure 4. The card e may then be mounted in the holder by inserting the hinge e in the open channel and sliding it into the slot b alongside of the hinge f2. The other hinge e2 may then be engaged similarly With the slot b2. Each of the cards may have tabs eX- posed to view at their lower edges as illustrated in Figure 8 for convenient selection.

It is to be undestood from the cepending application that in accordance with its disclosure, any desired number and arrangement of index card sheets Within certain limits can be brought together for support by a single pair of hinged elements andthereby introduced in and Withdrawn from the improved card holder a bv the simple manipula-tions described, regardless of the number oi such sheets involved. By providing a card holder Which will receive two pairs othin'ges1 even greater flexibility in the selection of sheets and greater capacity ot the tray are obtained.

That I claim is:

l. A stiff card holder formed as an open channel having two side Walls ot equal height throughout their length and having the edges or' the side Walls of the channel brought together at intervals to `form narrower slots.

2. A stift card holder formed as an open channel and having the edges ot the Walls of the channels brought together at intervals to vtorm narrower slots5 and other edge portions in engagement contiguous to said slots.

' 3. As an article of manufacture a unitary card holder formed from a blank ot sheet metal in Which the metal is drawn into chan- `nel form to provide a bottom and two side
